I'm wanting to really get into screen printing (beyond the hobby phase), and I'm wondering if anyone has experience with good blank T's and where they get them from. I really prefer made in the USA, but American Apparel is so expensive and the sizes run so small! Also, they no longer participate in co-ops, so I don't see an easy way to get less than 400 of something at a decent price.

I'm kind of in the same boat as you. Though they are expensive, my favorite tees are Alternative Apparel. They cost about $10 a piece for the ones I like, but I am figuring that into my end product's final price.

I'm also looking at https://www.royalapparel.net and "Bella" has some American made. There is also Loomstate, but I am not sure yet what their wholesale prices are. They may be really out of my price range.
